The dowdy peahen chooses the ornamental peacock as her mate. Male elephant seals use their bulk and weight to fight for a harem of females. A hornbill walls herself up for weeks and depends entirely on a devoted mate for food. Why such variety?

James Gould, a professor of biology at Princeton University, has an explanation for all mating habits - including our own. Every animal is in search of a bargain from the opposite sex. Every animal is doing its best to make sex pay.

The BAFTA Award-winning ballet celebrating the life and work of L.S. Lowry
Music composed by Carl Davis
Choreography by Gillian Lynne

Starring Christopher Gable, Moira Shearer
with Northern Ballet Theatre and members of the BBC Philharmonic Orchestra, conducted by Carl Davis

At the British Academy Awards in March A Simple Man won the Huw Weldon Award for Best Arts Programme. First shown in November, it tells the story of a man who is seen by many as one of the greatest British artists of the 20th century, L.S. Lowry. It deals with his struggle for recognition and with the search for his subjects.
Lowry declared his ambition was not to be a painter but was 'to put the industrial landscape on the map'.
The landscape he often chose was that around Salford. It was the City of Salford that first commissioned this evening's work. The programme is introduced by Albert Finney.

An eight-part series 6: Ships of Trade
Narrator Tim Pigott-Smith
The bulk of the world's trade has always been carried by sea, by sailing ships linking different peoples and cultures and bearing not cargoes of riches but the commodities of everyday life. The story of these ships is full of excitement, tragedy and inspiration. The
Amsterdam, entombed in the mud off Hastings since 1749, still loaded with an entire cargo. In the harbour entrance of St Peter Port a unique Romano-Celtic vessel of the time of Julius Caesar - recently snatched to safety from the paths of the Channel ferries. And, in Bermuda, the Sea Venture, whose loss in 1609 was immortalised by Shakespeare in The Tempest.
In bringing their stories back to life, marine archaeology is, in Sir Mortimer Wheeler 's phrase, 'not digging up things but digging up people'. Film editor JEFF SHAW Film cameramen

US Masters from Augusta National Golf Club
Who tonight will slip into the Green Coat, into the record books, and in the process find a crock of gold?
History, and the odds, favour another American winner, but the crest of the wave on which European golf now rides could swamp the home-based stars. Can Lyle, Woosnam, Faldo or Brown become the first Briton to triumph among the dogwood and azaleas of this magnificent course?
